Adult Health Exam 1
1. A client with a diagnosis of rheumatoid arthritis is prescribed methotrexate. What is the primary action of this medication?
- A. Increases joint lubrication
- B. Reduces inflammation by suppressing the immune system
- C. Enhances bone density
- D. Stimulates cartilage regeneration
Correct answer: B
Rationale: The correct answer is B: Methotrexate is an immunosuppressant that works by suppressing the immune system, thereby reducing inflammation in rheumatoid arthritis. Methotrexate does not directly increase joint lubrication (Choice A) as its primary action is on the immune system. Choices C and D are incorrect since methotrexate does not enhance bone density or stimulate cartilage regeneration. It is crucial for healthcare providers to understand the mechanism of action of medications to provide safe and effective care to patients.
2. The nurse is planning to ambulate a client who has been on bed rest for 24 hours following a Colon Resection. To ambulate this client safely, which intervention should the nurse implement first?
- A. Place non-skid shoes on the client
- B. Show the client how to use the call light
- C. Use a gait belt to support the client
- D. Assist the client to a bedside sitting position
Correct answer: D
Rationale: To ambulate a client safely after a period of bed rest, the nurse should first assist the client to a bedside sitting position. This initial step ensures the client is stable before attempting to stand and walk, reducing the risk of falls and allowing for a gradual adjustment to activity post-bed rest. Placing non-skid shoes, showing how to use the call light, or using a gait belt are important but should come after ensuring the client is safely seated and stable.
3. To assess pedal pulses, which arterial sites should the nurse palpate? (Select all that apply)
- A. Posterior tibial artery
- B. Radial artery
- C. External iliac artery
- D. Dorsalis pedis artery
Correct answer: D
Rationale: The correct answer is D: Dorsalis pedis artery. When assessing pedal pulses, the nurse should palpate the dorsalis pedis artery and the posterior tibial artery. The radial artery is located in the wrist and is not a site for assessing pedal pulses. The external iliac artery is not a correct site for assessing pedal pulses in the lower extremities, making it the correct answer.
4. A client has a prescription for a Transcutaneous Electrical Nerve Stimulator (TENS) unit for pain management during the postoperative period following a Lumbar Laminectomy. What information should the nurse reinforce about the action of this adjuvant pain modality?
- A. Mild electrical stimulus on the skin surface closes the gates of nerve conduction for severe pain
- B. Pain perception in the cerebral cortex is dulled by the unit's discharge of an electrical stimulus
- C. An infusion of medication in the spinal canal will block pain perception
- D. The discharge of electricity will distract the client's focus on the pain
Correct answer: A
Rationale: The correct answer is A. TENS units work by delivering small electrical impulses through the skin. These impulses are thought to close the 'gates of nerve conduction,' which can help in managing severe pain. Choice B is incorrect because the dulled pain perception does not occur in the cerebral cortex by the TENS unit. Choice C is incorrect as it describes a different method of pain management involving medication in the spinal canal. Choice D is incorrect because TENS does not work by distracting the client's focus on pain, but rather by altering pain perception through electrical impulses.
5. While caring for a client who is being mechanically ventilated, the nurse responds to a high-pressure alarm on the ventilator. Which assessment finding warrants immediate intervention by the nurse?
- A. Endotracheal cuff pressure greater than 25 cm H2O.
- B. Decreased lung compliance during ventilation.
- C. Bilateral crackles with increased secretions.
- D. Restless client who is biting the endotracheal tube.
Correct answer: D
Rationale: A restless client biting the endotracheal tube can increase airway resistance, triggering the high-pressure alarm and indicating a need for immediate intervention. This behavior can lead to complications such as dislodgement of the tube or airway obstruction. Endotracheal cuff pressure greater than 25 cm H2O, decreased lung compliance, and bilateral crackles with increased secretions are important assessments but do not directly address the urgent need to intervene when a high-pressure alarm is triggered.
